EXPLOSIVE WELDING OF METAL SHEETS

摘要

In this work explosive line and spot welding were used for the bonding of light-weight metal sheets. Materials involved are aluminum alloys 5052-O, 6061-T6, and 7075-T6, a magnesium alloy AZ31B-O and a commercially pure titanium (TP270C). Plates of similar and dissimilar metal combinations are explosion welded over a small overlapping area. The strength of the welds was measured using shear strength tests and the metal interface was analyzed using optical microscopy. The shear strength of the welds have been tested and appeared to high shearing strength. Explosive line and spot welding show a high strength to explosive mass ratio, making it a good candidate to be scaled up and used in commercial applications.
